Application June 24, 1946, Serial N o.. 678,831l

The invention relates to a burner unit and more especially to an oilburner unit for a furnace, stove or the like.

The primary object of the invention is to provide a unit of thischaracter, wherein the same can be installed within a furnace, stove orthe like, so that oil can be used as fuel with economy in consumptionand resultant maximum heating qualities, the unit being of novelconstruction, and unique in assembly.

Another object of the invention is to provide a unit of this character,wherein natural air is supplied thereto for proper combustion of thefuel oil, the latter being vaporized by the heat of the fire box orbasin and burned without smok- A further object'of the invention is toprovide a unit of this character, wherein it will burn any kind of oil,regular fuel oil, crude oil, kerosene, crankcase oil, etc., with minimumquantity required, for heating purposes.

A still further object of the invention is to provide a unit of thischaracter, which is simple in construction, thoroughly reliable andecient in operation, strong, durable, readily and easily installed,possessed of few parts, thus economical for repairs and replacements,assured of maximum heating quality and inexpensive to manufacture andinstall.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawings, which disclose the preferred and modified forms ofconstruction, and pointed out in the claim hereunto appended.

In the accompanying drawings:

Figure l is an elevation of a furnace, partly broken away, showing theoil burner unit constructed in accordance with the invention installed.

1 Claim. (Cl. 158-91) 2 z Referring to the drawings in detail,particularly Figures 1 to 5 inclusive, which is the preferred embodimentof the invention, A designates generally a greater portion of a hot airfurnace, yet it may be of any other type and as usual has a cylindricalshell or casing I0 provided in the lower portion thereof with a pit II,above which is disposed a refractory flame basin I2 having a cup-shapedor bowl formation I3, provided with a stepped annular wall I4 havingtroughs indicated at I5. This basin I2 at the periphery has contact withthe shell or casing IB, and is at rest upon a supporting ledge I6 builtwith such casing or shell, as best seen in Figure 1 of the drawf' ings,to be held in a horizontal plane therein.

The basin I2 centrally thereof is provided with a vertical passage, inwhich is snugly fitted a perpendicular tubular flue I'I providing an airinlet course from the pit II, and the upper end of the flue is providedwith a burner hood IB having a convexed top surface I9. Depending fromthe under face of the hood is a pair of spaced annular ribs 2li and 2|respectively, the rib 25 being deeper than the rib 2|. The ribs arepositioned over the trough formations I5. The flue I'I exteriorlythereof is provided with a stop ange 22 which seats against the flooringof the bowl I3 and thus the hood I8 is substantially level with theuppermost portion of the basin I2. The ribs depending from the hood I8coact with troughs I5 to define a tortuous path for the passagetherethrough of the products of combustion.

The nue I1 is provided with vents 23 forming air outlets to the bowlformation I3, while opening into the latter is an oil supply pipe 2li,which is passed vertically through the basin I2 and has union at 25 witha delivery pipe 26 leading from an oil supply tank 2l, which has hangerconnection 28 with a water reservoir 2S mounted uppermost of the shellor casing I0 exteriorly thereof, as best seen in Figure 1 of thedrawings. This pipe 26 is provided with an oil feed regulating control30 which is located in a discharge spout 3l unitary with the bottom ofthe tank 2l.

What is claimed is:

In a fuel burner unit, a shell, a basin arranged in said shell andprovided with a cup-shaped combustion bowl, there being a plurality ofcircular troughs arranged in said bowl, the outer periphery of said bowlbeing arranged in contact with the interior of said shell, ahorizontally disposed ledge projecting inwardly from said shell forsupporting said basin, there being a central passage in said basin, afirst vertically disposed pipe extending through the passage in saidbasin for conveying air to said bowl, a second vertically disposed pipeextending through said basin and arranged adjacent one side thereof forconveying fuel from a source of supply to said bowl, a circular hoodmounted on said rst pipe and having a conical top surface, a pluralityof spaced ribs depending from the under surface of said hood andcoacting with said troughs to define a tortuous path for the passagetherethrough of the products of combustion, the innermost ribs beinglonger than the outermost ribs, a horizontally disposed stop flangeprojecting outwardly from said rst pipe and abutting said basin, therebeing a plurality of air vents in said first vertically disposed pipe.
